4.11.4 Event log retrieve
4.11.5 Waveform capture data format
When a new event log coming, the newest event number address contains the newest
event number. When the log is being retrieved, the starting event log number and the event
quantity for each retrieve must be set correctly. It must be ensured that the starting number
of event log should equal or smaller than the newest log number. When setup is correct,
reading logging data registers will acquire the event log data. Each time a maximum of
9 logged events can be retrieved. The modbus register address of the event log retrieve
setting as shown in Table 4-13.

Waveform capture
AFM-8A series meter can record 8 groups of voltage and current waveform data at a
sampling rate of 64 points per cycle. It provides the captured waveform of 8 cycles before
and after the triggering point (including V1, V2, V3, I1, I2, I3). The triggering condition is
settable.
4.11.6 Waveform capture group
Waveform capture can log up to 8 groups of waveform data, the storage mode according
to the setting as below:
